Liquid crystal display with mirror face function

Abstract

A liquid crystal display with mirror face function, including a liquid crystal display module and a reflective element. A lower polarizing plate and an upper polarizing plate are respectively disposed on two faces of the liquid crystal display module. The reflective element is disposed on one face of the upper polarizing plate distal from the backlight element, whereby the reflective element can reflect part of external light to achieve a mirror-face effect. When the liquid crystal display module display a picture, the light emitted from the liquid crystal display module can pass through the reflective element to enhance the transparence.

1. A liquid crystal display with mirror face function, comprising a liquid crystal display module and a reflective element, a lower polarizing plate and an upper polarizing plate being respectively disposed on two faces of the liquid crystal display module, a backlight element being disposed on one face of the lower polarizing plate distal from the liquid crystal display module to serve as a light source of the liquid crystal display module, the reflective element being disposed on one face of the upper polarizing plate distal from the backlight element, whereby the reflective element can reflect part of external light to form a mirror face and when the liquid crystal display module display a picture, the light emitted from the liquid crystal display module can pass through the reflective element. 
   
   
     2. The liquid crystal display with mirror face function as claimed in  claim 1 , wherein the reflective element is a brightness enhancement film, the alignment direction of the brightness enhancement film being identical to the alignment direction of the upper polarizing plate, whereby when the liquid crystal display module display a picture, the light emitted from the liquid crystal display module can pass through the brightness enhancement film. 
   
   
     3. The liquid crystal display with mirror face function as claimed in  claim 1 , wherein the reflective element is a perforated reflective film, the perforated reflective film being formed with multiple perforations respectively corresponding to the pixels of the liquid crystal display module, whereby when the liquid crystal display module displays a picture, the light beam of the pixels can directly pass through the perforations. 
   
   
     4. The liquid crystal display with mirror face function as claimed in  claim 2 , wherein the brightness enhancement film is a dual brightness enhancement film (DBEF). 
   
   
     5. The liquid crystal display with mirror face function as claimed in  claim 1 , wherein a transparent substrate is disposed on one face of the perforated reflective film proximal to the liquid crystal display module.
